Peter - we have tried this both ways, default and certain package. The results
using the xmlns as you have described remains the same. It has become evident
that Saxon does not pay attention to the global classpath setting and as a
result cannot find my .jar. As a work around we have placed the .jar in
..\lib\ext and then are able to find it just fine. My target environment,
ultimately, is Unix where I anticipate things will work much better.

Does this sound correct to you?

Hi Steve,

Is your class in a certain package or is it in the default package?
Eg. If your class is in package com.medtronic.utils then you have to add the
package name to the namespace:
I use the same sort of calls and in my env it works like a charm (inside
Oxygen If you set the extensions correct and outside Oxygen if you set the
classpath right) If I remove part of the package name I receive the same kind
of error message.

Onderwerp: [xsl] How to call an external Java function

I have a working Java function that uses FontMetrics to determine the length
in points of a given character stream. I am able to call the function from the
windows command line and it runs just as I expect. Now I  want to call that
same function from my XSL stylesheet and I can't seem to get the correct

I have set my classpath environment variable to include the path:

I have placed FontWidth.jar in folder c:\maps-jars

FontWidth is the Java class.

And I have run the following simple transformation with Saxon8:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet  version="2.0"

    <xsl:template match="/">

        <xsl:variable name="testJava">
            <xsl:value-of select="med:labelStringWidth('Helvetica World', 12,
'This is test text')"/>

        <xsl:message>result:<xsl:value-of select="$testJava"/></xsl:message>



labelStringWidth is a method belonging to class FontWidth.

I have run this under <oxygen/> and stand alone from the command line with
Saxon8 and in both situations I receive the following error message:

Description: XPath syntax error at char 64 on line 11 in {...rld', 12, 'This
is test tex...}: Cannot find a matching 3-argument function named

Any help I can get on this would be very much appreciated.
